If you this function will be deleted in future php releases you can use this function:
<?
function _call_user_method_array($name, $obj, $params) {
// get params
$txt = "";
foreach($params as $nr => $el) {
$txt.='$params['.$nr."], ";
}
$txt = substr($txt, 0, strlen($txt)-2);
// run it
return eval('return call_user_method($name, $obj, '.$txt.');');
}
?>
Hope this helps somebody.
